Summary:
Observation 1: The solar flare and filament from yesterday were no longer visible with the camera. No sunspots could be seen with the eye, and the camera could not discriminate any from the granules.
Observation 2: I got a heads-up from Peter Detterline about a prominence on the Sun’s southeast side. It was not visible in the eyepiece at first, but after playing with the tuners it came into view. I attached the Skyris camera, brought the feature into focus, and took a capture.
Photos were taken with the Skyris camera and the best images processed in Autostakkert, Registax, Photoshop, and PowerPoint to colorize and bring out contrast. The results are attached.
Objects Viewed: Sun
Problems Encountered: Winds during second observation were such that I could not open the lower shutter without it shaking too much, so I kept it closed. The sun was high enough in the sky by then that I could observe it with just the upper shutter retracted.
